Development and validation of a model for evaluating aircrew checklists

For the past forty years, alternative methods and techniques have been researched and developed in light of reducing the burgeoning knowledge and memory requirements of individual workers. One such method is reliance on print-based job aids designed to reduce the amount of complex information that would otherwise be stored in working memory. Job aids are particularly useful where the transfer of skills and knowledge is critical, especially in high-risk industries, those industries in which task error can have serious consequences to property, environment, and life. This study focused attention on one specific format of job aids--the checklist.
